In order to study the pressure distribution of fully mechanized mining face, field measurement focusing on vertical stress was carried out by using micro-seismic and online stress monitoring system at 31102 working face in No. 2 mine of Nalinhe. The research showed that the lead influence distance of the auxiliary transportation roadway was 150 m,and the severe impact area appeared in 60 m ahead of working face,the hysteresis influence distance of the auxiliary transportation roadway was 350 m,and the severe impact area appeared in 150~300 m behind the working face, the lateral pressure peak was located in a pillar about 18 m away from the goaf; the auxiliary transportation chute should be strengthened in the area which ranged from 60 m ahead of working face to 300 m behind the working face; the application showed that this support distance met the need of strong mine pressure controlling.
